An American tourist
An American tourist was driving in County Kerry, when his motor stopped. He got out to see if he could locate the trouble. A voice behind him said, "The trouble is the carburetor." He turned around and only saw an old horse. The horse said again, "It's the carburetor that's not working." The American nearly died with fright, and dashed into the nearest pub, had a large whiskey, and told Murphy the bartender what the horse had said to him.

Murphy said, "Well, don't pay any attention to him, he knows nothing about cars anyway."

Brain or muscles?
The strong young man at the construction site was bragging that he could outdo anyone in a feat of strength. He made a special case of making fun of one of the older workmen. After several minutes, the older worker had had enough."Why don't you put your money where your mouth is," he said. "I will bet a week's wages that I can haul something in a wheelbarrow over to that outbuilding that you won't be able to wheel back.""You're on, old man," the braggart replied. "Let's see what you got."The old man reached out and grabbed the wheelbarrow by the handles. Then, nodding to the young man, he said, "All right. Get in."
